Description
When the powder mixtures of Zr/B/C=3/2/2∝6/10/1 in molar ratio were mechanically activated (MA) by ball milling and then exposed to air, they self-ignited spontaneously and the self-propagating high-temperature synthesis (SHS) was occurred to form ZrC and ZrB2 simultaneously. In this MA-SHS process in air, it is essential that graphite is converted into disordered carbon by mechanical activation and mixed with the particles of Zr and B in an intimate contact state. A fine, homogeneous microstructure of the product is expected to be a promising candidate as precursor of ZrC-ZrB2 composites. (orig.)
